28 SYSTEM CONFIGURATION
except with Hall and Theater modes, NO surround
channel bass will be sent to the subwoofer output.
When
NONEis selected, surround-sound infor-
mation will be split between the front left and
front right outputs. For optimal performance
when no surround speakers are in use, the Dolby
3 Stereo mode should be used.
When you are using surround back speakers with
your system, press the
¤
Button
E
on the
remote to move the cursor to
SURRBACK.
This line serves two functions in that it not only
configures the setting for the surround back
channels when they are present, it also tells the
AVR’s processing system to configure the unit for
either 5.1 or 6.1/7.1 operation.
Press the
‹
/
›
Buttons on the remote to select the
option that best describes the speakers in use at
the left and right back surround positions based
on the definitions on this page:
When
NONEis selected, the system will adjust
so that only 5.1-channel surround processing/
decoding modes are available and the surround
back amplifier channels will not be used.When
this is the case for your system you may wish to
take advantage of the availability of this amplifier
channel pair for use in powering a second set of
speakers that have their source selected by the
AVR’s multiroom control system. See page 38 for
more information.
When
SMALLis selected the system will adjust
so that the full complement of 6.1/7.1 surround
processing/decoding modes are available, and
low-frequency information below the crossover
point (identical with the one for the surround
speakers) will be sent to the subwoofer output
when the subwoofer is set to ON, or to the Front
LEFT/RIGHT when subwoofer is set to OFF.
When
LARGEis selected the system will adjust
so that the full complement of 6.1/7.1 surround
processing/decoding modes are available, and a
full-range signal will be sent to the surround back
channels, with no low-frequency information sent
to the subwoofer output.

the surround channels, press the
¤
Button
E
on the remote to move the cursor to SUB
MODE
.
8. Press the
‹

›
Buttons
E
on the remote to
select the option that best describes your system.
The choices available for the subwoofer position
will depend on the settings for the other speak-
ers, particularly the front left/right positions.
If the front left/right speakers are set to
SMALL, the subwoofer will automatically be set
to
SUB, which is the “on” position.
If the front left/right speakers are set to
LARGE, three options are available:
• If no subwoofer is connected to the AVR, press
the
‹
/
›
Buttons
E
on the remote so that
NONEappears in the on-screen menu.When
this option is selected, all bass information will
be routed to the front left/right “main” speakers.
• If a subwoofer is connected to the AVR, you
have the option to have the front left/right
“main” speakers reproduce bass frequencies at
all times, and have the subwoofer operate only
when the AVR is being used with a digital
source that contains a dedicated Low Frequency
Effects, or LFE soundtrack.This allows you to
use both your main and subwoofer speakers to
take advantage of the special bass created for
certain movies. To select that option press the
‹
/
›
Buttons
E
on the remote so that SUB
(LFE) appears in the on-screen menu.
• If a subwoofer is connected and you wish to
use it for bass reproduction in conjunction with
the main front left/right speakers, regardless of
the type of program source or Surround mode
you are listening to, press the
‹
/
›
Buttons
E
on the remote so that SUBL/R+LFE
appears in the on-screen menu.When this
option is selected, a full-range signal will be
sent to the front left/right “main” speakers.The
subwoofer will receive the front left and right
bass frequencies under the crossover frequency
selected in another setting on this menu, as
described below, and also the LFE soundtrack.
After making any required changes to the Sub-
woofer Mode line, press the
⁄
/
¤
Navigation
Button
E
to move the cursor to the SUB
SIZE
line. The setting on this line enters the
data of the size of your subwoofer’s driver so that
the proper gain, filters and equalization settings
will be used with EzSet/EQ.
To change the setting, make certain that the cur-
sor is on the
SUB SIZEline and press the
⁄
/
¤
Navigation Button
E
, so that the set-
ting appears that matches the diameter of your
subwoofer’s driver. If you do not remember what
the size is, you can either measure the driver’s
diameter or consult the owner’s manual for the
speaker.
When you have completed the settings for speak-
er “size”, press the
⁄
/
¤
Navigation Button
E
to move the cursor to the BACKTO
MANUALSETUP
line to continue your
adjustments. It is also important to remember to
re-run the EzSet/EQ system if any changes have
been made to the settings on this menu, follow-
ing the instructions shown on page 26 for using
the Manual mode.
Speaker Crossover Setting
When all initial speaker “size” settings have been
made, you now have the option to take advantage
of the AVR’s Quadruple Crossover system, which
allows individual crossover settings to be made for
each speaker grouping set to "Small".The low-fre-
quency crossover point is set by the design of your
speakers.
Note: if the Speaker is set to Large in Speaker
Size menu the crossover is automatically set to
40Hz when EzSet/EQ runs. It is defined as the
frequency which is the lowest possible frequency
the speaker is capable of reproducing, or the
frequency at which sound is sent to the speaker’s
internal low-frequency driver, as opposed to the
mid-range driver. The settings on the
SPKRX-
OVER
menu also allow you to set the high pass
filter that determines which frequencies go to the
subwoofer when the AVR 635 is playing back the
low frequency effects (LFE) channel from a digital
soundtrack.
Before making any changes to the settings for the
crossover point we suggest that you find the
crossover point for the speakers in each of the four
groupings, front left/right, center, surround and sur-
round back by looking at the specifications page of
the speaker’s owner’s manual, by getting that
information from the manufacturer’s Web site, or
by contacting your dealer or the manufacturer’s
customer service department.You will need this
figure to accurately configure the next group of
settings.
The factory default setting for all speaker positions is
100Hz. If that setting is acceptable for all channels,
then no adjustments are needed and you may skip
this section.
To make changes to the speaker crossovers or
LFE high-pass filter setting, go to the
SPKRX-
OVER
submenu within the MANUAL
SETUP
menu (Fig. 8).To do this, first press the
OSD Button
L
so that the MASTER
MENU
(Figure 1) appears. Next, press the
‹

E
until the cursor is on
the
MANUALSETUP line on the menu in use
and press the Set Button

.When the
MANUALSETUP menu is shown, press the

again until the
cursor is on the
SPEAKERX-OVER line and
press the Set Button
F
to view the SPKR
X-OVER
menu (Figure 10).

Buttons
E
until the cur-
sor is next to the line where you wish to make a
change and then press the

Buttons
E
until the desired setting appears. The available
choices at which point low-frequency information
will be sent to the subwoofer (or to the Front
Left/Right speakers in case subwoofer is set to
OFF), rather than to the speaker channel, are
40Hz, 60Hz, 80Hz, 100Hz, 120Hz, 150Hz and
200Hz. Pick the choice that is identical to the
information for the speakers, or if an exact match
is not possible, pick the closest choice that is
ABOVE the speaker’s lowfrequency limit to avoid
the creation of a low-frequency “hole” where
your system will have no bass information.
